Question

1. Frictional force is ____ of area of contact..​

Answer 1

The frictional force is independent of the area of contact

Explanation:

• The frictional force is only dependent on the type of the surface which is present. In case of smooth surface the force of friction is less as compared to of surface. Also the normal contact force plays an important role in determination of the frictional force.
• In case of a body which is lying on a horizontal floor the normal contact force is equal to the weight of the body.
